Our findings highlight that post-fire management that removes resprouting trees can unintentionally strip away critical food and shelter, and that tree composition (not just diversity) is key when assessing habitat quality for folivores before and after fire.

However, this is not true everywhere: forests dominated by a few low-protein or non-resprouting species may offer poor-quality habitat after fire.

In many mixed-species forests, #epicormic foliage can still provide enough protein and acceptable levels of defensive chemicals to support specialist leaf-eaters like koalas and greater gliders, helping surviving populations persist and recover.

After the 2019–20 Black Summer #fires, vast areas of eucalypt forest shifted from mature foliage to epicormic regrowth – the fresh shoots that emerge after fire. We analysed the chemistry of this regrowth and found it differs from mature #leaves in ways that depend on #eucalypt species and subgenus.

Chemical composition of post-fire epicormic foliage affects nutritional quality for folivores Forest fires can cause major changes in stand structure and habitat suitability for forest wildlife. For species that browse on foliage, the tree’s fi…

Excited to have our research on impacts of post-fire on nutritional quality in eucalypt forests for species such as the endangered southern #greaterglider and koala out this week in @elsevierconnect.bsky.social's Forest ecology and Management.

After decades of research, our new book on the eucalypts of WA's goldfields has finally arrived! Designed, compiled and printed in Australia.
Looking forward to hearing what everyone thinks of this one.

I recently gave a talk about Wilkerr (dingoes) at #ESA2025 (ecoevorxiv.org/repository/v...). Many call them 'wild dogs' in S.A. Below the dingo fence they are to be _eradicated_, by law. But the only true wild dog I knew of was the legendary dachshund, Valerie. #DadJokes @ecolsocaus.bsky.social

Very happy to have my #drone photo of East Gippsland’s beautiful lowland mixed species eucalypt forests printed alongside other amazing photographers and ecologists in the new @csiropublishing.bsky.social ,Ecology Matters’. Launched at this year’s @ecolsocaus.bsky.social #ESA2025 conference!

Big thanks to @deannicolle1.bsky.social for generously showing us around his Currency Creek Arboretum this morning. What a wonderful and unique place to explore all the wonderful Eucalypts that are out there! Great way to wrap up @ecolsocaus.bsky.social #ESA2025 in #adelaide.

Grateful that I got to present some of my fire research on beautiful #KaurnaCountry at #ESA2025

Big thanks to the Gulbali Collaboration Kickstarter award for getting me here.

Thermal drones are helping to monitor some of Australia’s most elusive wildlife Thermal camera-equipped drones are revolutionising wildlife surveys in Victoria’s native forests, say University of Melbourne experts.

Thermal drones are a promising tool for monitoring nocturnal arboreal wildlife, including elusive endangered species. They matched ground survey detection while covering more areas, greatly expanding our survey abilities. Read more: #unimelb Pursuit article: pursuit.unimelb.edu.au/articles/The...

Drone-derived densities for surveyed areas of 100–200 ha were significantly lower than those extrapolated from 10-ha ground survey results, indicating that ground survey transect placement, accessibility, vegetation density and habitat surveyed significantly drive resulting population estimates.

Drones achieved high detection rates for targeted wildlife and consistently recorded more species and individuals than ground-based surveys. Ground surveys often missed
specialist species like the endangered southern #greaterglider when populations had low densities.

We compared survey results from spotlighting on foot (4-10ha) with drones (up to 200 ha) that used thermal cameras to detect animals’ heat signatures and a zoom camera and floodlight to identify species. All target species were found and >1000 observations made: www.youtube.com/watch?v=6TjR...

Wildlife #surveys are vital for endangered species like the #greaterglider, which are usually counted on foot via #spotlighting, which is accurate but restricted in area. Drone tech enables larger scale surveys but had not been tested for arboreal fauna in native forests: youtu.be/xwKcCEbrFEA?...

Drones with thermal cameras are revealing the secrets of elusive Australian forest wildlife The new technology will help scientists monitor and protect some of Australia’s most iconic and threatened forest species.

Happy to be able to share that our work investigating the efficacy of thermal #drones for nocturnal #wildlife surveys is finally published in @esajournals.bsky.social Ecological applications: doi.org/10.1002/eap..... Find a summary in @theconversation.com here: theconversation.com/drones-with-...

@mandaloca2.bsky.social showing us that #dingoes have social networks too. Great talk on social interactions and drivers of population density of vulnerable Victorian dingoes at #iccb2025

At #ICCB2025? If you’re interested in #drones, arboreal #mammals and their recovery patterns in state #forests, I’d be keen to walk you through my poster! See me Monday at 4:30 PM - 6:00 PM in Great Hall 3 & 4 - Poster Board 32.

Looking forward to catch up with friends and colleagues soon!

High deforestation risk were consistently forecasted in lowland regions across four deforestation scenarios. This highlights the importance of protecting high diversity lowlands from future deforestation.

Was great to talk about our research in windthrow yesterday at the Ecological Society of Australia conference and have some great chats with people about their own observations across Australia.

Dr Tom @itsnotfairman.bsky.social boldly convinces us that severe wind is an under-appreciated disturbance in SE Qld. He urges us to consider extreme wind events as opportunities to do conservation mngmt like thin woody thickening, restore habitats, and reintroduce cultural burns. #ESA2024
